A method of surgically treating a patient suffering from severe pain and disability of the low back and buttock by stabilizing the patient's spinal column to their pelvis with an implant system including surgical tools and an implant designed to prevent movement between the sacrum and the ilium while being able to attach to a spinal fusion rod which connect to pedicle screws implanted in the bones of the spine of the patient in order to offer lasting relief of the patient's symptoms. The system is designed to address complications in adult spinal deformity by optimizing spinopelvic fixation via-a-vis the unique biomechanics of the SI joint. The sacropelvic system is a surgical solution which provides an additively manufactured implant at the base of the spine employing an S2AI trajectory while utilizing assisting technologies including surgical navigation and intraoperative neurophysiological monitoring.

Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. In one embodiment, a defect creation assembly is advanced from a posterior approach into the SI joint and configured to create pilot SI joint opening; portions of which being disposed in the sacrum and ilium bone structures. After the pilot SI joint opening is created, a prosthesis is press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures.

Systems are described for stabilizing a dysfunctional sacroiliac (SI) joint of a subject. The systems include a tool assembly and a defect creation assembly, and a prosthesis. The tool assembly is adapted to create a pilot SI joint opening in the dysfunctional SI joint; portions of which being disposed in the sacrum and ilium bone structures. The prosthesis is sized and configured to be press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures. The system optionally includes an image capture apparatus adapted to capture images reflecting positions and/or orientations of the tool assembly when disposed in the subject's body.

The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation and or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing and or stabilizing a plurality of bones is provided. The system includes an implant structure having a shank portion, a body portion and a head portion. The body portion is coupled to the shank portion and is configured to be placed through a first bone segment, across a bone joint or fracture and into a second bone segment. The body portion is configured to allow for bony on-growth, ingrowth and through-growth. The head portion is coupled to the proximal end of the shank portion and is configured to couple the shank portion to a stabilizing rod. Methods of use are also disclosed.

A sacroiliac joint fusion screw and associated delivery tools and method. Embodiments of the sacroiliac joint fusion screw comprise a shaft having proximal and distal end portions and a head on the proximal end of the shaft. A threaded portion on a distal portion of the shaft is configured to engage a sacrum. A glide zone portion on the shaft between the threaded portion and the proximal end portion is configured to extend through an ilium. The screw can provide stability and compression to the joint.

A fixation implant includes a head, a shank and a distal tip, and one or more of the head, shank and distal tip may be cannulated. The shank includes a threaded ingrowth portion extending from the head to the tapered distal tip that includes external threads, and at least one open network body extending along the length of the ingrowth portion. The open network body selected from one or a combination of a helix, an arrangement of trusses, a scaffold of open and interconnected pores, a porous framework of random open and interconnected pores, and combinations of these.

A biocompatible construction adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter distinct from the cutting edge. The rotatable cutter allows for graduated cutting of biological tissue or structure.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAT”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

An implant having an integrated cutting broach and/or cutting burr. The integrated implant may be inserted without requiring separate steps for drilling and broaching bone. The integrated implant assembly may include an integrated implant, a flexible sheath, a delivery rod, and a delivery pin. The implant may have a core which may have any of a variety of cross-sectional geometries. A method for fusing bone may involve inserting the implant laterally through the ilium, through the sacral-iliac joint, and into the sacrum.

Methods and apparatuses for performing an orthopedic procedure in the sacroiliac region are disclosed. In one form, an aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is inserted into the aperture. The undercutting system may include an insertion apparatus, a probe assembly, and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region.
